Stone & metal,
simply.

What sets the stones and metals we offer apart, in plain words, so you can choose the one that suits how you'll wear your ring.

I · The stone

Diamond or moissanite?

Natural and lab-grown are both real diamonds. Moissanite is a different stone that looks like a diamond, with its own kind of sparkle.

Natural & lab-grown diamond

Both are diamond

Think of it like ice: one froze in nature, the other in a freezer. It's the same thing, only made in a different place.

  • Shines a crisp, whiter light
  • More depth when you look into the stone
  • Generally cut more precisely
Moissanite

The diamond alternative

A different stone that looks very much like a diamond and costs much less.

  • More rainbow sparkle ("fire") in the light
  • Passes a diamond tester, because it carries heat almost the same way a diamond does
  • A beautiful choice when you want a bigger look for the budget

Lab-grown diamond

Same ice. Same hardness, same sparkle, same diamond. The difference is where it was made, and the price.

II · The metal

How much gold is in your gold?

9K, 14K and 18K are all real gold. The number tells you how much of the metal is pure gold. The rest is other metals, mixed in for strength and colour.

14K

18K

Gold bars show pure gold content; the platinum bar shows pure platinum content.

What really matters later

Day one, and two years on.

On the first day, every white metal looks bright. What sets them apart is how they look after a couple of years of wear.

Illustration for comparison. Real wear depends on how the ring is worn and cared for.

Keeping it white

A little care, every year or two.

Re-plate every 1–2 years

Gold is naturally yellow. White gold is gold mixed with white metals, then coated with rhodium to make it bright white. As the coating wears, the ring dulls and turns slightly yellow. A quick re-plate brings back the shine and the white colour.

Platinum

Naturally white, just polish

Platinum is white all the way through, so it never turns yellow. Over time it forms a soft grey layer called patina. A polish removes it, and a re-plate adds extra shine if you want it. It's also stronger than gold.

Our advice

Want it white, for life?
Choose platinum.

If you'd rather go with gold, 18K stays the shiniest and is the most forgiving if the ring gets knocked. 14K is the balanced choice, and 9K suits a smaller budget.
